To all whom t may concern Be it known that I, WILLIAM A. WARMAN,

a citizen of the United States, and a resident of which the following is a specification.

My invention relates to an improvement in power generators, the Vobject'thereof being to provide a device of this character, so constructed and assembled, vthat a much greater efficiency may be obtained therefrom than has heretofore been the case; which will be so constructed and arranged that the supply of fuel and air tol the combustion chamber will be automatically controlled in accordance with the pressure of the lhot gases generated, and wherein the temperature of the gases may alsobe automatically controlled whereby to avoid any and all danger of the destruction of any of the parts by reason of the excessive heat generated in the combustion chamber. f

With these, and other ends inI view the invention consists in certain novel features of construction and combinations of parts as will be hereinafter fully described and pointed out in the claims. f

In the accompanying drawings, Figure 1 is a view in side elevation of ay power generator constructed in accordancewith my invention; Fig. 2 is a sectional view taken combustion chamber. Y,

Referring to the drawings, 5 represents longitudinally through the water-jacketed a chamber, in the form of a receptacle, tube or cylinder, to one end of which is bolted or otherwise secured the cylinder 6,l surrounded by the water-jacket 7, the water chamber 8, the pipe, inder 6 communicating with the chamber and `forming a continuation thereof, as clearly illustrated in Fig. 2 of the drawings.

Into the cylinder 5, forming a part of the combustion chamber, are led the fuel and air, the fuel being such as is ordinarily emc ployed with internal combustion engines, as, for instance, gas, gasolene, oil, etc., and preferably under pressure, the fuel being supplied through the pipe 9 into a mixing chamber 10 connected with one end of the combustion chamber 5, this supply pipe be-`` 14, the lower end of saidlever 17 being and forming tube or cylw i 'y l',

ingvprovidedvwith a manually operated valve l1. To the mixing chamber 10 also leads the air supplypipe 12, this pipe being also providedwith a manually operated valve`13, as illustratedlin Fig. 1, this construction andiarrangement of parts permitting the supply 'of fuel and air to the mixing chamber 10 to be regulated or controlled, these several valves being provided in addition to automatic valves hereinafter referredto.

To the outlet end of the combustion cham` pipe, ytube or cylinder 14, f

engine (not having a lowco-eflicient of expansion, as,

for instance, invar, the opposite endv of this rody 16 being connected with a lever 17 fulcrumed in a ,bracket or support 18 rigidly connected `with or tothe expansion pipe connected with the valve stem 19 of the valve .20, said valve 20 beingalso carried by 4the 18,'the several parts' bracket ork support above mentioned comprising a thermostat to regulate the temperature -of the gases flowing through thecombustion chamber 7 and into the outletpipe 15 as will be hereinafter described.

Into the chamber 8 leads a water supply pipe 21, rand from said chamber leads the outlet pipe 22, the inlet pipe 21l beingl connected with any suitable sources of water supply, thefoutlet pipe 22 beingprovided in its lengthwith amanually operated valve 23. Saidy outlet pipe'is also connected with and controlledfby` the valve' 20,A from which latter the outlet pipe 22 leads into thecom-y bustionchamber 5,' as illustrated in Fig. 1.r

From the foregoing it will beunderstood pipes 9 and'12,and proportioned to give the the mixing chamber 10 and flow from 'the that the fuel and vairsuppliedthrough ythe proper combustiblefmixture, arey mixed in ber 5, where the mixture becomes ignited by the spark plug 23, or other suitable means, the ignited gas then flowing through the combustion chamber 6 and through the pipes 14 and 15 to the engine or other device employed for utilizing the power generator. As these hot gases pass through the tube or cylinder 14 the temperature thereof, if excessive, Vwill vexpand the said tube 14, the result being that the non-expansible member 16 will so operate the lever 17 as to open the valve 20, and thus permit water to flow from the chamber 8 through the pipe 22, throughthe valve? 20, through the pipe 22 leading from said valve 20, and into the combustion chamber 5, where it will mingle with the ignited gas to cool the sameto the desired degree. After the proper temperaturehas been secured,the cooled gas flowing through the tube or cylinder 14 will permit of the contraction ofthe same, causing the valve 20 in thewater pipe 22 to be closed, or Apartially so, and to so remain `until an excessive temperature of the gases causes the valve 2O` torautomatically open and again supply thefnecessary quantity of water to the combustion chamber. n

AWhile I have above described the use of water as'the cooling medium for maintaining the properv temperature in the combustion chamber, it will be understood without of the burning or destruction of any of the i 'further description or illustration that the device yis applicable for utilizing air or other gas as the cooling medium, the air being directed` through the pipes 21, through the `chamber 8, and out through the outlet pipe 22 into the combustion chamber 5, where it is mingled with the products of combustion in order to cool the latter, ex-

actly as in the case where water is employed.

I have found in practice that this construction and arrangement of parts is a very desir- .able one in that the temperature'of the working gases maybe `v ery accurately adjusted andk retained, avoiding any and all danger parts of the device by the excessive heat generated; furthermore, by forming the thermostatas a part'of theoutlet pipe from the combustion chamber, all the parts thereof are'easilyy and readily accessible for adjustment, and being exposed to the surrounding atmosphere f no danger of destruction thereof by the yheat of the gases exists.

In order to automatically Vcontrol the 'supply of fuel and air to the combustion chamber in accordance' withthe pressure of the gases in theoutlet pipe, and in order also to control the proper amount or supply of each to preservethe proper mixture for combustion, I provide in the fuel'inlet pipe 9 a valve 24 and inthe air supply4 pipe` 12 a yvalve 25,the former havingaflever 26 connected f therewith, `and thel latter having a llatter being also provided with two elongated slots 31 and 32, whereby the link 33 lever 27, each of said levers being provided at their outer free ends with an elongated slot 28, 29, respectively. Each of said levers 26 and 27 is linked to a lever 30, the

connecting the lever 26 to the lever 30, and the.link 34 connecting the lever 27 with the lever 30, may be so adjusted as to open and close the valves 24 and 25 to any extent desired with regard to the pressure of the gases in the outlet pipe 15, as will be hereinafter understood, and also to anyextent vas. may be desired with relation to each yconnected with the outlet'pipe 15 by a pipe 37, the result being that when the gases y flowing through the outlet 15 exert an excessive or too great a pressure, such pressure will be transmitted through the pipe 37 to the regulator 36, which, forcing the lever 30 downwardly by means of the rod 38' connected with the regulator and bearing against said lever, will cause the opposite end of said lever 30 to automatically close or partially close the valves 24 and 25 in the fuel and air supply pipes. When the pressure is released the lever 30 will again rise lto its normal position, permitting the valves 24'and 25'to also assume `their normal positions.

It will be seen that the combustion chamber 5 and the tube or cylinder 6 which communicates therewith are of relatively small capacity, so' that no considerable volume of 110 burning or burned gases is present in my device, the sustained pressure of the fluid under pressure produced being due to the continuous and uninterrupted supply of air and fuel to the combustion chamber; and it fol- 115 lows, because of the small rcapacity of the combustion. chamber, that no considerable volume of unburned gases can accumulate within the device, as is possible in similar devices which make use'of a comparatively 120 large storage tank, which unburned gases if allowed to accumulate to any extent within the tank will presently be ignited and an explosion will follow which may wreck the device, and which at any rate will produce waves of pressure are Inet with 'when the 130 same 1s 1n use; and, finally, such slight variations of pressure as may occur in the chamber in question are so damped, and reduced to such an extent, as to have but little if any effect upon the fuel and air controlling mechanism, because of the fact that the pipe 37 leading to said controlling mechanism communicates with the discharge or outlet pipe 15 at a point remote from the combustion chamber 'wherein such slight iuctuations of pressure as may occur in my device actually take place.

From the illustration, and from the above description, it will be understood that my improved generator is particularly simple in construction, of but few parts easily and readily accessible for adjustment and regulation, and wherein there is but little or no danger of getting out of order or being injured or destroyed by the hot gases; that the supply of combustible gas and the relative quantities of the fuel and air are automatically regulated by the pressure of the gases, and finally, that the temperature of the gases in the combustion chambers is also automatically regulated.
